Abstract
Abstract A method of treating acne by topically applying a member of a certain class of fatty acid amides to the affected skin area. Oleic acid diethanolamide is illustrated as a representative of the useful class. After cleansing, rinsing and drying the acne affected skin area to be treated, the fatty acid amide formulation is applied thereto and left thereon for beneficial action to occur. This manner of treatment is repeated as deemed necessary to control the acne condition.

Claim 1
Independent Claim

A METHOD FOR CONTROLLING ACNE WHICH COMPRISES TOPICALLY APPLYING TO AN ACNE AFFECTED SKIN AREA AN EFFECTIVE AMOUNT OF A COMPOSITION CONSISTING ESSENTIALLY OF A PHARMACEUTICALLY ACCEPTABLE CARRIER AND ABOUT 0.1% TO ABOUT 30% OF A DIETHANOLAMIDE OF A SATURATED OR UNSATURATED ALKANOIC ACID CONTAINING FROM 12 TO 18 CARBON ATOMS, INCLUSIVE, AND PERMITTING SAID COMPOSITION TO REMAIN ON SAID ACNE AFFECTED SKIN AREA TO ALLOW THE PERCUTANEOUS ABSORPTION THEREOF INTO THE SEBACEOUS GLANDS OF THE SKIN, WHEREBY THE ACNE CONDITION IN THE TREATED AREA IS CONTROLLED.
